  • Sag-Free Sofa: LAVEVE Heavy Duty Couch Cushion Support Review
Size: 21.5" x 70" - Couch
We all love sinking into a comfy sofa, but nobody enjoys that "falling into a black hole" feeling caused by sagging cushions. Enter the LAVEVE Heavy Duty Couch Cushion Support, a game-changer for saggy sofas. Measuring 20.5''x67'' and made from thick, solid wood, this support is here to save the day—and your back! The LAVEVE cushion support is crafted from thick, solid wood, making it incredibly sturdy. Unlike flimsy plastic or cardboard alternatives, this support won’t bend, buckle, or break under pressure. It’s designed to provide a firm foundation for your cushions, ensuring they stay in place and maintain their shape. Setting up the cushion support is a breeze. Simply unfold it and place it under your sofa cushions. The 20.5''x67'' size is generous enough to cover a wide area, making it suitable for most sofas. No tools, no fuss—just instant support. What I love about this cushion support is its durable material and easy-to-use design. The thick, solid wood construction means this support will last for years. Unfold, place, and enjoy a firmer seat—it’s that simple. The size is perfect for a wide range of sofas, providing comprehensive support. After installing the LAVEVE cushion support, I invited a friend over to test it out. He plopped down on the sofa with the force of a thousand suns, expecting the usual sag. Instead, he was met with solid support. His wide-eyed surprise was priceless. "Did you get a new couch?" he asked. Nope, just a little help from LAVEVE! The LAVEVE Heavy Duty Couch Cushion Support is a must-have for anyone dealing with saggy sofa syndrome. It’s durable, easy to install, and instantly improves the comfort and longevity of your couch. Say goodbye to the black hole effect and hello to supportive, comfortable seating. Highly recommended for anyone looking to give their old sofa a new lease on life! ... show more

  • No sinking but definitely durable and HARD
Size: 21.5" x 70" - Couch
Product came on time as said at time of purchase with no damage to box or packaging basic clear package nothing fancy. Boards they use for planks are very sturdy like said in description. The cloth that encases the boards seems durable and will protect my cushions from being ripped from the boards. They definitely work as described and I'm. Now not sinking into my couch. However it is quite firm now. About to replace the foam in the cushions hoping it helps but beware it's an adjustment. You will feel the difference and it might not be what you want ... show more

Only thing I dislike about it when you first put it on it falls through the boards in the futon. Sturdy, firmness, smooth, color is great can find where you put it. Great product!!!

  • Couch is like new!
Size: 21.5" x 70" - Couch
I have a hand me down sectional that was well loved before it came to me. The middle of the couches were sagging and I was getting frustrated that there was only one comfy spot. Else you’d start to lean into the center of the divot. At my wits end, I looked up ways to fix this issue and I discovered these! They’re so easy to use and I love that the wood boards are covered so you don’t need to worry about splinters. It’s just the perfect width to fit under the cushions but not stick out. Now my couch feels like it’s new! The extra support has been great and they’re very strong. Probably not recommended but I did walk on the couch and the boards didn’t snap so rest assured your booty will be safe! ... show more

  • Made a big difference in comfort
Size: 25" x 96" - Large Oversized Sofa
This made 3 year old "Bob's" L shaped sectional feel better than new.. Immediately the feel and seat of the sectional was firm feeling delightful. No more sinking and needing to get ready to stand up. No more adjusting the cushions every time someone gets up. This has changed the way we enjoy our living space for the better. Feels showroom new! ... show more

  • Not sure it will hold up
Size: 24" x 72" - Deep Couch
This was a good fit and installed easily, and it will definitely firm up my saggy sofa, but the boards aren't as rigid and sturdy as I thought they would be. I have my doubts about how long this product will hold up. It was a quick, cheap fix though, so it will do at least for a little while

  • Great purchase!
Size: 21.5" x 70" - Couch
My couch cushions were in rough shape and I wasn’t ready to buy a brand new couch. Decided to try a cheaper route. I made myself new cushions and while it was so much better, I decided to also add this cushion support. The couch feels brand new now. The cushion support was a game changer.

Fit perfectly in my couch and gave it much needed support just as described. Stays in place and gives the cushions added support that should greatly extend the life of my couch.
